S. C. HIGBIE, OF OPHENHEIM, NEW YORK.

PUMP.

Specification of Letters Patent No. 3,010, dated March 21V, 1843.

To all 'whom t may concern Be it known t-hat I, S. O. HIGBIE, ofOphenheim, in the county of Fulton and State of New York, have inventeda new and useful Improvement in the Construction of Pumps; and I dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,making a part of this specification, in which a vertical section of thepump is shown.

The nature of my *invention consists in constructing' a double actionforcing' pump, by cast-ing it intwo pieces, with air chambers and allentire; which can be keyed together with two keys, and made perfectlytight.

An oblong box (a) isformed, with a vertical cylinder (b) at each end.These cylinders are perfectly air tight at top, and open into the boxbelow. Near each of these cylinders there is a hole (c) in the top ofthe boX, and at the center there is a similar hole (CZ), through thebottom, around which a flange projects down. On each side of the hole(fl) is placed a hook (e) with the lip projecting inward partly over theflange. Around the flange a ring ts, the lower edge of which turnsinward.. The supply pipe (g) is furnished with a flange at its upper endover which the ring (f) is put. A ring of leather is put between the topof the supply pipe and the flange, and they are held firmly together, bymeans of wedges (i) driven in between the lower edge of the ring (f),and the hooks (e) This casting is firmly held to the bottom of the sink,or other convenient plank (n), by means of wedges (7c) driven throughstaples (Z) cast on the bottom of the box at each end.

The air cylinders (b) has a recess on the inside at (b) for a smallspace, above which the upper part of the cylinder projects over. Themiddle compartment (m) of the upper casting can be made of any desiredform and is the air chamber; it projects up, and forms the fulcrum ofthe pump handle, to be hereafter described. Near the top of this airchamber, an air cock (m) is situated; and near the bottom the nozzle(mf) is inserted. At the bottom of the chamber, the sides projectinward, and form piece at each end; this piece is dividedat its 1 center(n3) where there is an extension screw (n3) to press its two ends apartagainst the hinge of the valve; a top plan of it is shown at F ig. 2. Oneach side of the air chamber (m), pump cylinders (0) are cast, and intowhich the hole (n) opens;

in each of the cylinders (o) a plungerY (p) works, which is attached tothe pump handle l (g) by means of the connecting rod (Q), which isjointed thereto and also to the plunger. On the outside of the cylinder(0) there is a projection (0), that fits into the recess in the side ofthe cylinder the upper part of which cylinder fits against (0). Betweenthe top of the box #(a), andY the bottom of the cylinders (0), and airchamber (m), there is a leather packing (7') A valve (11') is cut out ofthis near each end, at the hole (c) in the top of the boX, which isdirectly under the pump cylinder (o),v and through which the water isdrawn, on the rising of the plunger. When the plunger demands, the valveV(r) shuts, and valve (n) opens, and admits the water into the airchamber. Thechamber (m), and cylinders (0), are rmly attached to theboX, by means of the wedge (s), which is driven in between the upperside of the projection (0') and the top of the recess in cylinder (Z1)which secures them together and keeps the packing (1') tight.

)(Vhat I claim as my invention and desire to secure by Letters Patent,isy 1. The mode herein set forth of constructing the pump in two partswhich have but one packing and are keyed together in the manner hereinset forth. l

2. I also claim the method of holding .the valves (n) in place by meansof the T iron (n) constructed and arranged as herein fully made known. Y

S. O. VIfIIGrBIE.
